While I jogged down the local running trail about seven in the morning, a boy of about ten years old passed me. I did a double take but didn’t see any parents around. Two things occurred to me: 1) kudos to that kid, he rocks, and 2) how old should a kid be before he/she is allowed to exercise alone?

As a someone without kids but hopefully someday, I’m curious where parents draw the line. I’d assume that distance, place, and age play a huge role. What do you think? When would you let your kid go out for for a couple mile run or bike ride?
